I have used3', 5' and 7' threaded leaders (thanks Betty and Jack) on my 7' 4wt boo and really like them. A couple of friends of mine have been using mono furled leaders on their graphite rods and told me I should give them a try. I have used some of the thread leaders for dry fly fishing but am not sold on them when nymphing with an indicator. Feather Craft sells them according to rod weight and in different lengths. I was thinking either 6' or 7' since I do both dry fly fishing and nymphing.
I would appreciate suggestions.
